Introduction

Midjourney is an AI image service provided by Ace Data Cloud, enabling Midjourney AI image generation. Through the unified API of Ace Data Cloud, you can quickly integrate Midjourney using JavaScript to achieve text-to-image, image editing, image description, image-to-video, seed control, asynchronous callbacks, and other features.

​
Prerequisites

  • Have an Ace Data Cloud account and obtain an API Token
  • Node.js 18+ or a modern browser environment

​
Basic Usage

The main endpoint for calling the Midjourney API is: 
POST https://api.acedata.cloud/midjourney/imagine
Complete JavaScript code example: 
const response = await fetch("https://api.acedata.cloud/midjourney/imagine", {
  method: "POST",
  headers: {
    "Authorization": "Bearer YOUR_API_TOKEN",
    "Content-Type": "application/json",
  },
  body: JSON.stringify({
  "prompt": "A serene Japanese garden with cherry blossoms",
  "action": "generate",
  "mode": "fast",
  "translation": true
}),
});

const result = await response.json();
console.log(result);
Please replace YOUR_API_TOKEN with the actual token you obtained from the Ace Data Cloud platform.

​
Response Handling

It is recommended to check the response status code and handle errors: 
if (response.ok) {
  const result = await response.json();
  console.log("Call succeeded:", result);
} else {
  console.error(`Call failed, status code: ${response.status}`);
  const error = await response.text();
  console.error(error);
}

​
Node.js Wrapper

It is recommended to encapsulate into a reusable function: 
async function callMidjourney(data) {
  const response = await fetch("https://api.acedata.cloud/midjourney/imagine", {
    method: "POST",
    headers: {
      "Authorization": `Bearer ${process.env.ACE_API_TOKEN}`,
      "Content-Type": "application/json",
    },
    body: JSON.stringify(data),
  });
  if (!response.ok) throw new Error(`API error: ${response.status}`);
  return response.json();
}

​
